澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票1. Before the installation of air ducts and components, remove internal and external sundries and dirt and keep them clean. When installing the air duct, in order to facilitate installation, try to connect it on the ground if conditions permit, and generally connect it to about 10 ~ 12m long.

2、风管法兰垫料按系统进行选用。空调、通风风管采用厚度为3mm的8501密封胶带密封,排烟系统风管采用石棉橡胶板作为法兰垫料。

2. The air duct flange gasket shall be selected according to the system. The air conditioning and ventilation ducts are sealed with 8501 sealing tape with a thickness of 3mm, and the air duct of the smoke exhaust system uses asbestos rubber plate as flange gasket.

3、法兰垫片厚度为3~5mm,垫片要与法兰齐平,不得凸入管内,以免增大空气流动阻力,减少风管的有效面积。

4、紧固法兰螺栓时,用力要均匀,螺母方向一致。风管立管法兰穿螺栓,要从上往下穿,以保护螺纹不被水泥砂浆等破坏。

4. When tightening flange bolts, the force shall be uniform and the direction of nuts shall be consistent. The air duct riser flange shall be threaded from top to bottom to protect the thread from being damaged by cement mortar.

5. The air duct passing through the roof shall be provided with rain cover; The riser 1.5m out of the roof must be reliably fixed and intact, and there shall be no defects such as cracks, loose bite and holes, so as to prevent rainwater from leaking into the room from the air duct. When the air duct passes through the wall and floor, the surrounding gaps shall be densely filled with fireproof flexible materials.

6、穿越沉降缝风管之间连接及风管与设备连接的柔性短管采用外刷防火漆的帆布制作。在风管与设备连接柔性短管前,风管与设备接口必须已经对正,不得用柔性软管来作变径、偏心。安装柔性短管时应注意松紧要适当,不得扭曲。空调支管至风口之间的连接采用带保温层的金属软管,软管与风口及与风管接口采用专用的卡箍进行连接。软管较长时,必须在中间部位设置吊架,但金属软管的长度不得超过2米。

The flexible short pipes connecting the air ducts passing through the settlement joint and connecting the air ducts with the equipment shall be made of canvas coated with fireproof paint. Before connecting the flexible short pipe between the air duct and the equipment, the interface between the air duct and the equipment must be aligned, and the flexible hose shall not be used for reducing and eccentricity. When installing the flexible short pipe, pay attention to the proper tightness without distortion. The connection between the air conditioning branch pipe and the air outlet adopts the metal hose with thermal insulation layer, and the hose is connected with the air outlet and the interface with the air duct with special clamps. When the hose is long, a hanger must be set in the middle, but the length of the metal hose shall not exceed 2m.

7、风管与配件可拆卸的接口及调节机构等,不得装设在墙或楼板内。

7. The detachable interface and regulating mechanism of air duct and accessories shall not be installed in the wall or floor.
